Subject: [PATCH] A more compatible fix to MK_META_MODE not being defined.
 Also, encase bmake specific constructs not needed for make bootstrap so fmake
 doesn't see them. This works with fmake just well enough for us to build
 bmake to build the rest of the tree without fatal errors. Tested only with
 fmake package.
